[0001] This utility model relates to the field of desulfurization wastewater treatment technology, specifically to an online desulfurization wastewater mixing and energy-saving and environmentally friendly treatment device for coal fed into the furnace. Background Technology

[0002] Online desulfurization waste liquid is a waste liquid containing high concentrations of sulfates, heavy metals and by-product salts generated in wet desulfurization processes (such as coke oven gas purification or flue gas desulfurization in coal-fired power plants). Direct discharge will pollute the environment, so it is necessary to treat it in an energy-saving and environmentally friendly manner. To this end, we propose an online desulfurization waste liquid mixing with coal fed into the furnace for energy-saving and environmentally friendly treatment. Utility Model Content

[0003] The technical problem this invention aims to solve is to overcome existing defects and provide an online desulfurization wastewater mixing and energy-saving environmental protection treatment device for boiler feed coal. During use, the feed assembly delivers the feed coal into the boiler body, while the liquid delivery assembly delivers the desulfurization wastewater into the dispersion assembly. The dispersion assembly not only evenly distributes the feed coal to various locations within the boiler body but also evenly sprays the desulfurization wastewater onto the feed coal at each location. This utilizes the high temperature inside the furnace to achieve evaporation and harmless treatment of the wastewater, while simultaneously recovering the potential heat energy from the wastewater. This can replace some fuel consumption, reduce carbon emissions, and thus achieve the goal of energy-saving and environmental protection treatment, effectively solving the problems in the background technology.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an online desulfurization waste liquid co-mixing energy-saving and environmentally friendly treatment device for boiler coal, comprising a boiler body, a bag filter, a liquid delivery component, and a dispersion component;

[0005] A sliding groove is provided on the middle side of the boiler body, and a sealing plate is slidably installed in the sliding groove. A handle is installed on the outer side of the sealing plate. The inner wall of the boiler body and the upper surface of the sealing plate form an upper cavity, and the inner wall of the boiler body and the lower surface of the sealing plate form a lower cavity. A liquid feeding assembly is installed on the right side of the upper surface of the boiler body. Multiple first legs are evenly installed on the lower surface of the boiler body. A slag discharge assembly is installed in the middle of the lower surface of the boiler body. A connecting pipe is connected to the side wall of the lower cavity. Multiple second legs are evenly installed on the lower surface of the bag filter. The outer end of the connecting pipe is connected to the air inlet of the bag filter. An exhaust pipe is installed at the air outlet of the bag filter. A dispersion assembly is provided in the upper cavity, and a feeding assembly is provided on the upper surface of the boiler body.

[0006] Furthermore, the dispersing component includes a rotating shaft rotatably mounted on the middle of the upper surface of the boiler body. A convex diversion cover is installed on the inner wall of the upper cavity. The rotating shaft and the convex diversion cover are rotatably connected. Multiple through holes are uniformly opened on the upper surface of the convex diversion cover. Multiple arc-shaped grooves are uniformly opened at the edge of the upper surface of the convex diversion cover. Multiple connecting rods are uniformly installed on the lower outer surface of the rotating shaft. An arc-shaped plate is installed at the end of the connecting rod. Multiple round holes are uniformly opened on the arc-shaped plate. A second gear is installed on the rotating shaft. A rotating shaft is rotatably mounted on the upper surface of the boiler body.

Installation pipes are installed on both sides of the middle part of the rotating shaft. The installation pipes communicate with the cavity. Multiple spray heads are uniformly installed on the lower surface of the installation pipes. The lower end of the liquid delivery component is rotatably connected to the inner wall of the cavity of the rotating shaft. After passing through the feeding assembly, the coal enters the boiler and falls into the convex diversion cover. Under the action of multiple uniform through holes, it is diverted to various locations within the boiler body. The coal that slides onto the outer edge of the convex diversion cover falls mechanically under the action of the arc groove. Simultaneously, the drive assembly operates, causing the rotating shaft to rotate. The rotating shaft rotates the first gear, which in turn rotates the second gear and the rotating shaft. The rotating shaft rotates the connecting rod and the arc plate, thereby evenly dispersing the coal into the edges of the boiler body through multiple rotating arc plates and the round holes on the arc plates. At the same time, the liquid delivery assembly delivers desulfurization waste liquid into the cavity and sprays it onto the coal in the boiler through the installation pipe and spray head. The rotation of the rotating shaft also drives the installation pipe to rotate, so that the spray head evenly sprays the desulfurization waste liquid onto the coal in the boiler under the action of the rotating installation pipe.

[0007] Furthermore, the drive assembly includes a motor bracket mounted on the upper surface of the boiler body, on which a motor is mounted. The output shaft of the motor is connected to the upper end of the rotating shaft via a coupling, and the input end of the motor is electrically connected to the output end of an external controller. The external controller controls the motor's operation, which in turn drives the rotating shaft to rotate, thus electrically completing the rotation of the rotating shaft.

[0008] Furthermore, the slag discharge assembly includes a slag discharge pipe connected to and installed in the middle of the lower surface of the boiler body, and a control valve is installed on the slag discharge pipe. The slag discharge is accomplished through the slag discharge pipe and the control valve.

[0009] Furthermore, the feeding assembly includes symmetrically arranged feeding ports on the front and rear sides of the upper surface of the boiler body, and a feeding plate is rotatably mounted inside the feeding port via a pin. The feeding port can be opened or closed by rotating the feeding plate.

[0010] Furthermore, the liquid delivery assembly includes a waste sulfur tank installed on the upper surface of the boiler body. A water pump is connected to the left side of the waste sulfur tank, and an inlet pipe is installed at the outlet of the water pump. The lower end of the inlet pipe is located inside the cavity of the rotating shaft, and the lower end of the inlet pipe is rotatably connected to the inner wall of the cavity of the rotating shaft. The desulfurization waste liquid in the waste sulfur tank is delivered into the cavity by the operation of the water pump to complete subsequent work.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This online desulfurization waste liquid mixed with coal fed into the boiler is used to feed coal into the boiler body through the feeding component. At the same time, the liquid feeding component feeds the desulfurization waste liquid into the dispersion component. The dispersion component not only evenly distributes the coal fed into the boiler body to various locations, but also evenly sprays the desulfurization waste liquid onto the coal fed into the boiler at various locations. This utilizes the high temperature inside the furnace to achieve evaporation and harmless treatment of the waste liquid, while recovering the potential heat energy in the waste liquid. This can replace part of the fuel consumption, reduce carbon emissions, and thus achieve the purpose of energy-saving and environmental protection. Attached Figure Description

[0016] Please see Figure 1-2 This embodiment provides a technical solution: an online desulfurization waste liquid mixed with coal for energy-saving and environmentally friendly treatment, including a boiler body 1, a bag filter 15, a liquid delivery component and a dispersion component;

[0017] A sliding groove is provided on the middle side of the boiler body 1, and a sealing plate 4 is slidably installed in the sliding groove. A handle 11 is installed on the outer side of the sealing plate 4. The inner wall of the boiler body 1 and the upper surface of the sealing plate 4 form an upper cavity, and the inner wall of the boiler body 1 and the lower surface of the sealing plate 4 form a lower cavity. A liquid feeding component is installed on the right side of the upper surface of the boiler body 1. Multiple first legs 2 are evenly installed on the lower surface of the boiler body 1. A slag discharge component is installed in the middle of the lower surface of the boiler body 1. A connecting pipe 16 is connected to the side wall of the lower cavity. Multiple second legs 17 are evenly installed on the lower surface of the bag filter 15. The outer end of the connecting pipe 16 is connected to the air inlet of the bag filter 15. An exhaust pipe 14 is installed at the air outlet of the bag filter 15. A dispersion component is provided in the upper cavity, and a feeding component is provided on the upper surface of the boiler body 1.

[0018] During operation, coal is fed into the boiler body 1 via the feeding assembly, while desulfurization waste liquid is fed into the dispersing assembly via the liquid feeding assembly. The dispersing assembly not only evenly distributes the coal into various locations within the boiler body 1, but also evenly sprays the desulfurization waste liquid onto the coal at each location. This utilizes the high temperature inside the furnace to achieve evaporation and harmless treatment of the waste liquid, while also recovering the potential heat energy from the waste liquid. This can replace some fuel consumption, reduce carbon emissions, and thus achieve the goal of energy conservation and environmental protection.

[0019] The dispersion assembly includes a rotating shaft 3 rotatably mounted on the middle of the upper surface of the boiler body 1. A convex diversion cover 25 is installed on the inner wall of the upper cavity. The rotating shaft 3 and the convex diversion cover 25 are rotatably connected. A plurality of through holes 26 are evenly opened on the upper surface of the convex diversion cover 25. A plurality of arc-shaped grooves 27 are evenly opened at the edge of the upper surface of the convex diversion cover 25. A plurality of connecting rods 23 are evenly installed on the lower outer surface of the rotating shaft 3. An arc-shaped plate 24 is installed at the end of the connecting rod 23. A plurality of round holes are evenly opened on the arc-shaped plate 24. A second tooth is installed on the rotating shaft 3. A rotating shaft is rotatably mounted on the upper surface of the boiler body 1. A first gear 5 is mounted on the rotating shaft. The first gear 5 and the second gear 10 are meshed together. A drive assembly is also mounted on the upper surface of the boiler body 1. The drive assembly is connected to the upper end of the rotating shaft. A cavity 22 is opened inside the upper end of the rotating shaft 3. An installation pipe 20 is installed on both sides of the middle part of the rotating shaft 3. The installation pipe 20 is connected to the cavity 22. Multiple spray heads 21 are evenly installed on the lower surface of the installation pipe 20. The lower end of the liquid delivery assembly is rotatably connected to the inner wall of the cavity 22 of the rotating shaft 3. After passing through the feeding assembly, the coal enters the boiler body 1 and falls into the convex diversion cover 25. Under the action of multiple uniform through holes 26, it is diverted to various positions within the boiler body 1. The coal that falls onto the outer edge of the convex diversion cover 25 is mechanically dropped by the arc groove 27. At the same time, the drive assembly drives the rotating shaft to rotate, which in turn drives the first gear 5 to rotate. The first gear 5 then drives the second gear 10 and the rotating shaft 3 to rotate. The rotating shaft 3 then drives the connecting rod 23 and the arc plate 24 to rotate. Thus, the coal is evenly distributed to the edges of the boiler body 1 through the multiple rotating arc plates 24 and the round holes on the arc plates 24. Meanwhile, the liquid delivery assembly delivers the desulfurization waste liquid into the cavity 22 and sprays it onto the coal through the installation pipe 20 and the spray head 21. The rotation of the rotating shaft 3 also drives the installation pipe 20 to rotate, so that the spray head 21 evenly sprays the desulfurization waste liquid onto the coal under the action of the rotating installation pipe 20.

[0020] The drive assembly includes a motor bracket 6 mounted on the upper surface of the boiler body 1, a motor 7 mounted on the motor bracket 6, and the output shaft of the motor 7 connected to the upper end of the rotating shaft via a coupling. The input end of the motor 7 is electrically connected to the output end of an external controller. The external controller controls the operation of the motor 7, which drives the rotating shaft to rotate, thereby completing the rotation of the rotating shaft electrically.

[0021] The slag discharge assembly includes a slag discharge pipe 13 connected to and installed in the middle of the lower surface of the boiler body 1, and a control valve 12 is installed on the slag discharge pipe 13. The slag discharge is completed through the slag discharge pipe 13 and the control valve 12.

[0022] The feeding assembly includes symmetrical feed ports on the front and rear sides of the upper surface of the boiler body 1, and a feed plate 8 is rotatably mounted inside the feed port via a pin. The feed port is opened or closed by rotating the feed plate 8.

[0023] The liquid delivery assembly includes a waste sulfur tank 19 mounted on the upper surface of the boiler body 1. A water pump 18 is connected to the left side of the waste sulfur tank 19. An inlet pipe 9 is installed at the outlet of the water pump 18. The lower end of the inlet pipe 9 is located inside the cavity 22 of the rotating shaft 3, and the lower end of the inlet pipe 9 is rotatably connected to the inner wall of the cavity 22 of the rotating shaft 3. The desulfurization waste liquid in the waste sulfur tank 19 is delivered into the cavity 22 by the operation of the water pump 18 to complete subsequent work.

[0024] The working principle of the online desulfurization waste liquid mixed with coal fed into the boiler provided by this utility model is as follows: During use, the coal fed into the boiler body 1 is sent into the boiler body 1 through the feeding component. At the same time, the liquid feeding component sends the desulfurization waste liquid into the dispersing component. The dispersing component not only evenly distributes the coal fed into the boiler body 1 to various positions, but also evenly sprays the desulfurization waste liquid onto the coal fed into the boiler at various locations. Thus, the high temperature inside the furnace is used to achieve the evaporation and harmless treatment of the waste liquid, while recovering the potential heat energy in the waste liquid. This can replace part of the fuel consumption, reduce carbon emissions, and thus achieve the purpose of energy-saving and environmental protection treatment. After passing through the feeding assembly, the coal enters the boiler body 1 and falls into the convex diversion cover 25. Under the action of multiple uniform through holes 26, it is diverted to various positions within the boiler body 1. The coal that falls onto the outer edge of the convex diversion cover 25 is mechanically dropped by the arc groove 27. At the same time, the drive assembly drives the rotating shaft to rotate, which in turn drives the first gear 5 to rotate. The first gear 5 then drives the second gear 10 and the rotating shaft 3 to rotate. The rotating shaft 3 then drives the connecting rod 23 and the arc plate 24 to rotate. Thus, the coal is evenly distributed to the edges of the boiler body 1 through the multiple rotating arc plates 24 and the round holes on the arc plates 24. Meanwhile, the liquid delivery assembly delivers the desulfurization waste liquid into the cavity 22 and sprays it onto the coal through the installation pipe 20 and the spray head 21. The rotation of the rotating shaft 3 also drives the installation pipe 20 to rotate, so that the spray head 21 evenly sprays the desulfurization waste liquid onto the coal under the action of the rotating installation pipe 20. The motor 7 is controlled by an external controller, which drives the rotating shaft to rotate electrically. The slag is discharged through the slag discharge pipe 13 and the control valve 12. The feed inlet is opened or closed by rotating the feed plate 8. The desulfurization waste liquid in the waste sulfur tank 19 is pumped into the cavity 22 by the water pump 18 to complete subsequent operations.

[0025] It is worth noting that in this embodiment, the core chip of the external controller is an STC microcontroller, specifically the STC15W204S, while the motor 7 can be freely configured according to the actual application scenario. The external controller controls the operation of the motor 7 using methods commonly used in existing technologies.
